` vThis invention relates to a spinning vframe oi that type usually referred to as a wet spinning frame; and has for one oi' its objects to provide 4an' arrangement of the frame whereby the same. eiective functions of the frame may be obtained v with the occupatlonorflessarea'orgoor space,A -thus enabling a 'greaternumber of 'frames-to be g placed ,vinto a givenjiloor space for operatiim. A more speciiic object-of theinventio'n is to so arrange a' frame that it will 'oe-narrower Vin struction heretofore made.

Anothenobject of the invention isy to provide for a'greater exibiiity of-control of the liquid applied to the yarn prior to its spinning.

Another object of the invention is-toimprove the view of the yarn.

A more specic object of the invention is to apply liquid to the yarn rather than immerse the yarn in the liquid itself. Y

with these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a sectional view largely diagrammatic, looking endwise of the machine equipped with my invention;

Fig. 2 is a fragmental sectional view on a larger`scale, illustrating the container for the liquid which is applied to the yarn; a

Fig. 3 is a diagrammatic view of the drive for vthe `liquid-amuying roll; and

Fig. 4'is a fragmental view, illustrating an adljustment for the rods-which carry the supporting brackets. f

In a wet spinning frame of this'character it has been usual to ,mount the container for the liquid to be applied to the yarn at approximately the same vhorizontal level as, or just below, the nip rolls, and back of the nip rolls which hold the twist being 'put in the yarn. The container for the liquid is of considerable breadth and requires the frame tofbe of substantial width in order that .the liquid container may be accommodated; and in order to make the frame of narrower construction and retain all of the effectual advantages of a frame of this character, I have elevated the liquid-containing trough and placed the nip rolls and supply package beneath portions of the trough, whereby I am able to make a frame of much less width and yet one which is fully as efcient functionally as the previous machine which occupies a greater amount of space.

Furthenby this arrangement I have been able to convey the yarn across the top of an applicator roll whereby I may both govern the extent of contact ofgthe yarnA with the roll and by the speed of the roll, govern -the amount ofv liquid applied `to theyarmand further, by arranging this ap- -plicator roll at about eye level .the observation of itsactionmaybe more readily observed; and the the'preferre'd-meansby-which these advantageous results may be accomplished:

With reference 'to the drawings, the frameworkconsists of a main de'sk, designated I0, with legs, I I'extendlng' downwardly therefrom. Packagesof'twisted'yarn are designated I2, suitably supported on spindles drventhrough'f the V`whorls .I3 by belts lIl engaging driving drums vIii extending the length of the frame with an individual take-up pulley I6, all mounted upon suitable framework I1 of the machine. There is a ring rail I8 and ring I9 through which the yarn 20 is delivered to the package I2, the same being guided through the thread board guide 2l extending from the thread board 22 and then by a ring traveler on the ring, all of which may be movabie from a suitable builder motion guided by rods 23 and bosses 24.' This is all usual con-4 struction of the frame.

Nip rolls 25 and 26 are mounted in ay stand 21 which is supported upon the deck III, while just rearwardly of these 'niprolls there is -located a supply package'o! yarn 28. An upright standard 29 is supported upon the deck I0 and extends to a suilicient height to support the trough 30 clear above the supply package 28. This trough contains a liquid 3| such, for instance, as oil, which Y is tobeapplied to the yarn prior to its being twisted between :the nip of the rolls 25 and 26 '4o and the .ring traveler which guides the yarn about the package I2.

This liquid trough assembly is Vof considerable lateral dimension (see Fig. 2) and comprises a casting Il which extends from one upright standard 2l on one side of the machine to another upright standard 2!l on the other side of the machine, while a suitable pan 3 0 extending lengthwise of the machine removably rests upon and is supported between such laterally-extending brackets or castings 33 located at spaced intervals along the machine. Driven applicator rolls 34 are supported in bearings from the castings 3l and positioned to revolve partially immersed in the liquid 3| to pick up the liquid and apply it to the yarn. Pig-tail yarn guides 36 are mounted following is-.a moredetailed description oi the 10 present embodiment o'f this invention-,illustrating width than frames o f similar capacity and con-v in bars Il for guiding the yarn 3S on one side of the roll while brackets 5l mounted on rods Il support, rods Il carrying pig-tail guides 35 on the other side of the roll through which the yarn l! extends so as to contact the roll 34 and receive therefrom the liquid to be applied to the yarn.- The liquid-applying mechanism above described for' one sideof theframe is duplicated on the other s'ide of the frame, th'e frame of course being the usual back-to-back arrangement of operating parts. l

'I'his arc of contact may be governed by an adjustment. of the pig-tail guides. The bars I1 on either side of the machine carried by the bracket 60 may be adjusted by rotation of the rods Il upon which these brackets are mounted by means of the'clamp screws 52, there being segmental gears 53 meshing with each other s'o that the rods 6| will be simultaneously rotated such, for instance, as through segment 54 mounted on one of the rods 5l and worm 55 having crank 5B. These gears may be mounted at one end of the frame for manual manipulation. After rough adjustment of the pig-tail guides 35 is thus accomplished, finer adjustment g5 may be had by screwing either one of the pigtail guides 35 or more or less into the bars which support them. 'I'he thread on each guide is of such a ilneness that one complete turn or several complete turns will be utilized for such The bars carrying the pig-tail where adjustment. guides may have a. traverse motion desired.

'I'he rolls 34 are driven, and the speed of rotation of these rolls will also vary the amount of 3g liquid picked up and applied to the yarn; that is, if the rolls are driven fast, more liquid would be picked up and applied to the yarn than if they were driven slow. This speed may be governed at the head end of the machine where the '40 gear box is located, there being -a drive gear 5l and a driven gear 5l on the end of the shaft for rolls 3| with a change gear 52 for the purpose of securing the desired rotation of the rod shaft.

It will be apparent that as the yarn 39 is led from the supply package, it will extend upwardly over the guide bar Il, thence through the inner guide I8, over the roll 3l and through the front guide thence forwardly over guide Il through pig-tail guide 42 about the lower nip roll 25 between the rolls 25 and 25; and thence through the traveler I! on the ring Il andto the package I2. Rotation of the package will draw the yarn through the traveler and will place the desired twist in the yarn.

A standard I5 extends upwardly from the bracket 33 with pins 45 projecting in either direction; thus, fresh supply packages Il or empty bobbins or completed work may be placedl upon these pins for convenient storage until it is desired to use the same.

By the arrangement which I have just described, the broad liquid-containing trough assembly is elevated so that a very narrow deck III may be provided, and thus the entire width of the machine reduced.

Further, the yarn which travels from the supply package through the moistening device is so arranged that the amount of moisture to be applied to the yarn may be very readily adjustedand yet a large amount of storage due to the 1. In a wet spinning frame, a trough for liquid to be applied to the yarn, a roll revolvable in said liquid, guides for the yarn on either side of said trough to cause the same to contact said roll at least tangent thereto, all of the guides on one side of the roll being supported on a common bar and means to adjust said bar to simultaneously adjust the guides on one side of the roll.

2. In a wet spinning frame, a trough for liquid to be applied to the yarn, a single roll revolvable in said liquid, guides for the yarn on either side ofthe roll to cause the yarn to contact said roll-at least tangent thereto, all of the guides on one side of the roll being supported on a common bar, means to adjust said bar to simultaneously adjust the guide secured thereto, and means to drive the roll to govern the amount of liquid applied to the yarn.

3. In a wet spinning frame, a main deck, legs to support the same, nip rolls for controlling the point of yarn twist supported by said deck and above the same, a yarn supply also supported by said deck, laterally extending brackets, a trough for containing liquid to be applied to the yarn supported on said brackets, an upright standard supporting said brackets at a height substantially above said rolls and yarn supply, and means for storing the bobbins supported by said brackets.

4. In a wet spinning frame, nip rolls for controlling the point of yarn twist, a yarn-supply package supported at substantially a common horizontal level with said rolls and laterally spaced therefrom, and a liquid-applying means for the yarn occupying a greater lateral space than the said lateral space between said rolls and the said package and located at a height and position to overlie said lateral space.

5. In a wet spinning frame, nip rolls for controlling the point of yarn twist, a yarn-supply package supported at substantially a common horizontal level with said rolls and laterally spaced therefrom, and a liquid-applying means for the yarn occupying a greater lateral space than the said lateral space between said rolls and the package and located at a height and position to overlie said lateral space and overlie a portion of said rolls and liquid-applying means.

6. In a wet spinning frame, a main deck, legs to support the same, nip rolls for controlling the point of yarn twist supported by said deck and above the same, a yarn supply package also supported by said deck and'laterally spaced from said nip rolls, a trough for containing liquid to be applied to the yarn of greater lateral dimen sion than the space between said rolls and said yarn-supply package, and an upright standard supporting said trough at a height substantially above said rolls and yarn supply package and directly above said space.
